Abstract
Description
- The present invention relates to a cover, and in particular to a cover for sterilizable medical containers to improve the handling, storage and organisation of such containers after sterilization.
- Reusable medical devices, such as instruments, need to be sterilized before re-use. Often steam based sterilization systems are used to sterilize the instruments. Sterilization systems typically include a container, such as a rigid exterior perforated case of either a metal or plastic material and having a rigid lid. Instruments are often held in a tray which is placed in the case. Multiple trays can be stacked within the same case. Common sterilization practices require the cases to be wrapped in a sheet or sheets of a wrapping material which provide a sterile barrier to maintain the sterility of the instruments after sterilization. The wrapping material, sometime referred to as "bio-wrap", is often provided as sheets of paper of fabric and one or more sheets of the wrap are used to wrap the cases prior to sterilization so that the outer wrapping maintains the sterility of the cases post sterilization.. This can create a large amount of disposable waste.
- The sterilized wrapped cases are then placed in hospital storage rooms until transport to the operating room is required. However, the wraps are susceptible to rips and tears which compromise the sterility of the instruments within the case. Also, the uneven wraps tend to make it difficult to stack and organise the cases on the shelves in the storage rooms. Sometimes, when trying to remove a case from a stack of cases, the wrap around the case being removed or other cases in the stack can be damaged thereby compromising sterility. Also, other cases in the stack or in adjoining stacks can be dislodged from the shelves and fall to the floor again damaging the wrap and sometimes spilling the content of the cases. Handles placed on the exterior of cases are not accessible when the tray is wrapped. The wrapping material makes it difficult to transport wrapped containers and the lack of proper handles leads to ripping of the wrap. In an attempt to clasp onto the handle mechanism of the case under the wrap, fingers can penetrate the wrap and again compromise the sterility of the instrument case. Whenever the sterility has been compromised or possibly compromised, it is necessary to re-sterilize the case and contents which is a drain on the sterilization resources available to the hospital and can lead to understocking of sterilized instruments available for use.
- Attempts at ameliorating these problems have focussed on removing the necessity for the use of bio-wraps through the use of a sterile container or a disposable filter bag in place of the wrapping material. However, many sterilization facilities still use the practice of wraps to maintain sterility during storage and transportation.
- Therefore there is a need to improve the maintenance of sterility during storage and handling of wrapped sterile medical containers.
- The present invention provides a cover to go around the outside of the wrapped container which acts to hold the wrap against the container and helps protect the wrap from damage and also includes a handle to facilitate handling of the wrapped container. Hence, the cover helps to reduce damage to the wrap material during storage and handling of the sterile containers and thereby helping to maintain their sterility and reduce the number of containers that need to be resterilized.
- According to a first aspect of the present invention, there is provided a cover for a sterilizable medical container wrapped in a wrapping material. The cover can include a body having an upper part configured to at least partially cover and/or hold the wrapping material against an upper portion of the container. The body can also include a lower part configured to at least partially cover and/or hold the wrapping material against a lower portion of the container. The body can be assembled about the wrapped container to at least partially cover and/or hold the wrapping material about the container. The cover includes at least one handle extending from the body. The handle can be held by a user to handle a covered wrapped container when the cover is assembled about the wrapped container.
- By at least partially covering the wrapping material, damage to the wrapping material can be reduced thereby helping to maintain the sterility of the container and its contents after sterilization.
- By holding the wrapping material against the container, the cover also to keep the wrapped container more tidy, which helps to improve the handling, storage and manipulation of the covered container, thereby also helping to reduce damage to the wrapping material and hence improving sterility.
- Further, by providing a handle as part of the cover, a user can use the handle to manipulate and mover the covered wrapped container and so the user does not need to handle the wrapping material itself, which yet further helps to reduce damage to the wrapping material and hence helps to maintain sterility.
- The cover can be made of a sterilizable material. Hence, the cover can be applied before sterilization. Such as cover is also re-usable as it can be sterilized again after use.
- The handle can be provided as an integral part of the body. This can simplify manufacture of the cover as the handle is formed as part of the main body of the cover.
- The body can have a generally rectangular shape and the handle can be provided on the shorter side of the body or on the longer side of the body.
- The cover can include a plurality of handles. Preferably the cover can includes two or at least two handles. A first handle can be provided at a first end of the body. A second handle can be provided at a second end of the body. The second end can be at an end opposite to the first end. A handle can be provided at each end of the body and at the ends separated by the longest dimension of the body.
- The body can be permeable to steam. The material of the body can be made of a material which is itself permeable to steam. The body can include a plurality of apertures to make the body permeable to steam. This facilitates the ingress and egress of steam during sterilization when the cover is made of a material which is not itself permeable to steam.
- The cover can include a fastener for securing the cover about the wrapped container. The fastener can secure the upper member and lower member together when the cover is assembled about the wrapped container. The fastener can be a single use fastener or the fastener can be a releasable fastener. The fastener can be a mechanical fastener or can be an adhesive fastener.
- The cover or body can be made from a single sheet of material. The cover can be assembled about the wrapped container by folding the sheet of material. The sheet of material can be engineered to cause the sheet to fold along preferred lines or directions. The sheet of material can include at least one or a plurality of fold formation which define where the sheet of material can be folded to assemble the cover. The fold formations can be positioned on the sheet to define the upper and lower portions and at least a first side portion and preferably also a second side portion. The fold formations can be positioned so that the cover when assembled will snugly accept a wrapped sterilizable medical container.
- The cover can be made from a cardboard. The cover can includes an adhesive material positioned on the cover so that the adhesive material can be used to secure the cover about the wrapped container when the cover is assembled about the wrapped container.
- The cover can be made from a plastic material.
- The sheet of material can include cuts which help to define how the sheet of material can be folded to assemble the cover.
- The cover can include at least one retaining formation to help retain the wrapped container within the cover. The or each retaining formation can be located toward an open end of the cover. The or each retaining formation can act to prevent the wrapped container from escaping from the cover via the open end of the cover. The retaining formation can be provided as an integral part of the cover. The retaining formation can be formed by bending or folding a part of the material of the cover. The or each retaining formation can be defined by at least one cut line or fold formation. The or each retaining formation can be located adjacent the handle at an end of the cover. Preferably at least one retaining formation is provided at each open end of the cover.
- Instrument cases are often marked with information concerning the interior contents. After the case is wrapped this information is hidden. Hospital staff sometimes create labels to mark the interior contents of the wrapped container, however this manual process is tedious and prone to error. Therefore, the cover can bear one or more indicia indicating information relating to the contents of the container. The information can relate to a manufacturer of the contents, a model name of the contents, the type of the contents, the size of the contents, other attributes of the contents and any combination thereof.
- The cover can comprise two separate members which can be joined together to assemble the cover about the wrapped container.
- Each of the two separate members can be the same as the other. That is the members can each have the same shape and construction. Hence, only a single type of member needs to be manufactured and the members can be used interchangeably in a modular fashion.
- Each member can be generally tray shaped. Each member can be generally rectangular with a low wall extending generally around its periphery. Each member can be made of a thermoformed plastic.
- An outer surface of the cover can present a guide formation which allows another cover to be slid along a longitudinal axis of the cover.
- An outer surface of the cover can present a guide formation which allows the self aligned stacking of covered wrapped containers.
- An outer surface of the cover can present a guide formation which prevents sliding of another cover in a direction generally perpendicular to a direction along which the covers can be slid.
- The guide formation can be in the form of at least one ridge and at least one groove. Preferably a plurality of ribs and grooves are provided. The ribs and grooves can be provided as an integral part of the body of the cover.
- The cover can be generally dimensioned to receive a sterilizable medical container when at least partially covered by a wrapping material. The cover can be dimensioned to receive a container having dimensions in metres of height, width and depth selected from:0.05 by 0.25 by 0.50; 0.10 by 0.25 by 0.50; 0.15 by 0.25 by 0.50; 0.05 by 0.25 by 0.25; and 0.10 by 0.25 by 0.25.
- A further aspect of the invention provides a method for covering a sterilizable medical container wrapped in at least one sheet of wrapping material. The method can include placing the sterilizable container wrapped in the wrapping material onto a lower part of a cover. The cover can then be assembled about the wrapped container so as to at least partially cover and/or hold the wrapping material against the container. The cover can then be secured about the wrapped container.
- The method can further comprise sterilizing the wrapped container after being covered by the cover.
- The wrapped container can already be sterilized before being covered by the cover.
- A further aspect of the invention provides an assembly comprising: a sterilizable medical container; wrapping material wrapped around the container; and a cover around the wrapped container.
- The cover can include any of the features of the cover identified above.
- The assembly can further comprise a medical device in the medical container.
- The medical device can be an orthopaedic device. The orthopaedic device can be an implant or instrument or tool or similar.
- The medical container, any contents of the container and the wrap can all be sterile.

- With reference to
Figure 1 there is shown a first embodiment of acover 100 for assembling about a wrapped sterilizable container. The container may be a case or similar, or simply a tray holding whatever is to be sterilized. In the following, the container will generally be used to refer to any structure which is used to hold or support whatever is being sterilized during the sterilization process. For example, the container may refer to a case with a one or more trays located therein or simply to a sterilizable tray, or similar, or multiple trays or similar. - The
cover 100 is in the form of a foldable flat 102 made of a cardboard material. In other embodiments, the foldable flap may be made from a plastics material. - The foldable flat 102 includes a number of
fold formations 104, being parts of the cardboard flat which have been engineered are otherwise adapted to cause the cardboard material to preferentially fold along that line, in a desired direction. The engineered folds 104 to 114 are positioned on the flat so as to define portions corresponding to first and second side walls, and upper and lower portions or surfaces of the container to be covered. For example,portions Portion 124 also includes anaperture 126 therein which provides a window via which information about the contents of the container on a printed sheet can be viewed. - A
first handle portion 128 and asecond handle portion 130 are provided at first and second ends of the flat respectively. Each handle portion includes ahandle formation Handle portion 130 also includes a strip ofadhesive material 136. The adhesive material can be used to provide a fastener to secure the cardboard flat in its assembled configuration when assembled about a wrap container in use.Adhesive material 136 can be a contact adhesive which adheres to acorresponding part 138 ofhandle portion 128. In alternative embodiments, adhesive 136 may be covered by a releasable cover strip which is removed prior to assembly of thecover 100. - As described above, it will be appreciated that the cover generally has a main body section with an
integral handle formations foldable flap 102 can easily be manufactured simply by a stamping process in which the apertures are created by a cutting instrument acting on a sheet of cardboard material and in which thefold lines 104 to 114 are created by a scoring, or similar, process. In an alternate embodiment, portions of the body of thefoldable flap 102 are provided with a plurality of apertures arranged generally all over the body in order to allow the ingress and egress of steam during sterilization. - With reference to
Figures 2A to 2D , use of thecover 100 will be described in greater detail.Figure 2A shows a plurality ofcovers 100 as illustrated inFigure 1 . Acover 100 in an unassembled state is selected and the sterilized container covered by at least one sheet of wrappingmaterial 150 is placed on thelower part 120 of thecover 100, as illustrated inFigure 2B . As illustrated inFigure 2C , assembly of the cover is commenced by folding the cover alongfold line portion 122 of the cover engages a rear side of the wrapped container and eventually, by further folding cover alongline 110, theupper portion 124 of the cover is brought into contact with the upper portion of the container.Portions portions region 138 and thereby secures the cover in its assembled formation about the wrapped container as illustrated inFigure 2D . Hence, the end result is anassembly 160 comprising thecover 100 assembled about the wrappedcontainer 150 as illustrated inFigure 2D . - As can be seen, the cover holds the sheet of wrapping material about the container and also at least partially protects the wrapping material by generally enclosing it. The
cover 100 also presents ahandle 162 by which the container can be more easily handled during storage or movement by a user. - As illustrated in
Figure 1 , in the first embodiment, thecover 100 has a generally rectangular shape and the handle extends along a one of the longer sides of the cover.Figure 3 shows a second embodiment of thecover 200, generally similar to the first embodiment shown inFigure 1 . Cover 200 also has a generally rectangular shape, but handle 202 extends along and from a shorter side of thecover 200. It was also illustrated inFigure 3 ,aperture 204 in the upper part ofcover 200 provides a window by which a user can view information about the contents of the sterilized container presented on a sheet ofpaper 206. -
Figure 4 illustrates athird embodiment 220 of the cover. This embodiment is similar to the first embodiment except that it does not include a window aperture. As also illustrated inFigure 4 , the cover can bear at least one indicium on an outer surface of thecover 220 which provides information about the content of the container. For example, thecover 220 can include an indication of the manufacturer of the contents, the type or nature of the contents, for example, the name or type of an instrument, information about the size of the contents and/or any other properties or attributes of the medial instruments or devices held in the container. - With reference to
Figure 5 , there is shown a plan view of afourth embodiment 230 of a cover according to the invention. Thecover 230 is in the form of a foldable flat 232 made of a plastics material, such as polypropylene, or a thermoformable material or plastic Thecover 230 is shown in an unassembled state and is assembled about a wrap container in use, as will be described in greater detail below. - The plastics flat 232 includes a number of apertures and cuts in the plastics material and also includes engineered fold formations, e.g. 234, 236 to allow the flat to be folded along preferred directions. A

The first and second halves are then drawn toward each other which causes the flat to become assembled and wrap around the wrapped container andflap 250 is inserted intoslot - Hence, in this assembled state, the cover generally wraps around the wrapped container so as to hold the wrap against the container and also generally protect the wrap from damage.
- In order to facilitate handling of the covered wrapped container, a user folds
flaps - With reference to
Figure 6 , there is shown a fifth embodiment of acover 290 according to the present invention. Thefifth embodiment 290 is generally similar to thefourth embodiment 230 and is also provided in a form of a foldable plastics flat 292.Figure 6 shows further fold formations not necessarily shown inFigure 5 . The flat also includes a mechanism to retain the wrapped within the foldable flat to prevent the container sliding out of the cover along the longitudinal axis of the cover. The mechanism is illustrated in greater detail inFigure 7 which shows a perspective view of thecover 290 when assembled in use about a wrappedcontainer 300. A illustrated best inFigure 6 , towards each of the four corners or shoulders of the flat 294, 296, 298, 300, a retaining formation is provided by a cut and a fold formation, e.g. cut 302 and foldformation 304. When the cover is assembled about the wrapped container, generally as described above, the retaining formation is provided by folding a strip of plastics material aboutfold formation 304 so as to provide a barrier extending from the lower part of the cover to the side wall of the cover so as to prevent any movement of the wrap container along the longitudinal axis of the cover. -
Figure 8 shows a plan view of a sixth embodiment of thecover 310 generally similar to the embodiments shown inFigures 5 and6 . Again, thecover 310 is provided in the form of a foldable plastics flat 312 and is shown inFigure 8 in an unassembled configuration. Cover 310 is similar to cover 290 in that it includes a retention mechanism to help prevent longitudinal sliding of the wrapped container within the cover in use. A retention mechanism is provided at each end of the cover. The retention mechanism takes the form of a generallyU-shaped portion central portion 260 of the flat and which each bears a pair oftongues slot -
Figure 9 shows a magnified perspective view of a corner of thecover 310 when assembled in use about a wrappedcontainer 340. After the first and second halves of the upper portion have been drawn together and fastened bytongue 250 in one ofslots U-shaped members tongues slots tongues slots e.g. portion 344 provides a strap which engages about the end of the wrapped container to restrict its movement along the longitudinal axis of the cover. - With reference to
Figures 10 and11 there are shown perspective views of a seventh embodiment of acover 350 according to the invention. Thecover 350 is in the form of a pair of generally tray-shapedmembers Figure 12 . Each generally tray-shapedmember handle portion strap head portion re-entrant aperture - The main body of the cover includes a central large
rectangular aperture 380 which provides a window via which information can be viewed. The main body of the cover also includes a plurality of lozenge or oval shaped apertures to allow the ingress and egress of steam during sterilization. As best illustrated inFigures 10 and11 , the sequence of convex ribs and concave grooves are provided on the outer surface of each tray member. The rib and grooves alternate and are dimensioned so that a rib from a one cover will mate with a groove from another cover on which it is stacked so as to allow the stacked covered containers to be slid laterally relative to each other but to prevent sliding in a direction generally transverse to the longitudinal axis of the cover, as will be described in greater detail below. - The cover is made up from two identical tray portions, as illustrated in
Figure 12 , with a first of the tray portions receiving the wrapped container therein and a second tray portion inverted and placed over the top part of the wrap container as illustrated inFigures 10 and11 . Between them the tray parts provide the main body of the wrapper with the handle formations providing a handle at each end of the cover which is integral to the main body of the cover. The tray members are identical and so can be used inter-changeably in a modular fashion. Hence, it is only necessary to manufacture one type of member which can then be used as either the upper or lower part of the cover. The parts of the cover are fastened together in the assembled state by engaging stems 360, 362 in corresponding apertures in the upper inverted tray and engaging similar stems in the upper inverted tray into theapertures - Use of
cover 350 is generally similar to use of the other embodiments as described above. The wrapped container is placed in a lower tray and an inverted upper tray is placed over the wrapped container and the parts fastened together to assemble the cover about the wrap container. That assembly can then be sterilized with the plurality of apertures in the main body of the cover allowing the easy passage of steam into and out of the wrapped container. After sterilization, the assembly can be moved using the handles and the sterilized assembly stored in stacks of similar assemblies in a storage facility. As mentioned above, the outer surfaces of the upper and lower trays present a number of convex ribs, e.g. 382, and a number of concave similarly shaped troughs, e.g. 384. Similarly shaped ribs and troughs are provided between the plurality of apertures either side of themain viewing aperture 380. When stacked, the ribs and troughs of the upper surface of a lower tray can engage with the troughs and ribs respectively of a lower surface of an adjacent upper tray. The ribs and troughs extend generally along the longitudinal axis of the cover and are generally elongate and straight and facilitate the sliding of trays relative to each other in the longitudinal direction. This can facilitate the removal of a tray from within a stack of trays without interrupting the stability of the stack. - Also, the interaction of the ribs and troughs help to prevent sliding of trays within a stack of trays in a direction generally transverse to the longitudinal axis of the cover. For example, if a stack of several assemblies is being carried to or from the store room, then this helps to prevent trays from sliding off the stack in a transverse direction which can otherwise happen.
- The interaction between the ribs and troughs, or ridges and grooves, also helps to provide self-alignment of the stacked trays. Further, the grooves provide an air space which improves the effectiveness of the sterilization. As discussed above, the interaction of the ridges and grooves also provides stability for stacks of trays during transportation.
- This embodiment of the cover is particularly preferred as it is quicker and easier to assemble about a wrapped container than the other embodiments. Also, it is easily adjustable to accept wrapped containers of different sizes. As would be appreciated, as each tray component is identical, it is only necessary to fabricate a single type of item and then each tray can be used with similarly shaped trays in a modular system in order to provide the cover.
- In practice, the tray can be thermoformed from a thermoplastic material, such as polypropylene, and the tray can be thermoformed using a heat based moulding process. A preferred gauge for the polypropylene material is approximately 0.04 to 0.06 inches. Other suitable thermoformable plastics which can be used to fabricate the cover include polyethylene and acrylonitrile butadiene styrene (ABS).
- As will be appreciated from the above discussion of the invention, it provides a number of advantages and solves a number of problems associated with wrapped sterilizable medical containers. The cover of the invention helps to retain the wrapping material about the container in a tidy manner which helps to facilitate handling and storage of the wrapped containers. Also, the cover serves to at least partially protect the wrapping material thereby helping to reduce the incidence of damage or tearing of the wrapping material. Further, the covers provide a generally flat surface which further facilitates the storage by stacking of multiple wrapped containers. Further, the covers facilitate access to information about the contents of the wrapped container so that it is easier to ensure that the correct sterilized contents are retrieved from a store when required. Yet further, the integral handle further facilitates the handling and manipulation of the wrap container so there is no need to grasp the wrapping material or try to access any handle on the container as the cover provides an easily accessible handle to a user.
- The exact dimensions of the cover, and the position of the various cuts and fold marks in the various embodiments, will depend on the size of container or tray with which it is intended to use the cover. For example, sterilizable containers or trays are generally provided with dimensions of height by width by depth or approximately 5 x 25 x 50, 10 x 25 x 50, 15 x 25 x 50, 5 x 25 x 25 and 10 x 25 x 25 (all measurements in centimetres). It will be appreciated that the cover can be used with other sizes of sterilization trays or containers as required. Therefore, the dimensions of the cover will generally match the dimensions of the container to be covered, but with some tolerance to accept the sheet or sheets of wrapping material in which the container has been wrapped.
- In other embodiments of the invention, the cover can be dimensioned to accept multiple containers therein. For example, a cover can be provided which can accept a stack of individual trays or containers. Additionally or alternatively, covers can be provided with fastening mechanisms which allow the size of the cover to be adjusted depending on the size of the container to be covered. For example, the fastening mechanism of the seventh embodiment could include a
longer stem portion lugs - It will be appreciated that various features of the invention have been described in the different embodiments thereof. The invention should not be considered to be limited only to the specific embodiments described but various features of the different embodiments can be used in combination with other features of the various embodiments unless mutually exclusive. It will be understood by those skilled in the art that changes in the form and the details of the disclosed embodiments may be made without departing from the spirit or scope of the invention. Therefore the scope of the invention should be determined with reference to the appended claims.
